Perfection of a Kind
"Perfection, of a kind" symbolizes the prejudicial concept of the existence of a superior race. Nazi dictator Adolf Hitler is the obvious literal inspiration for the tyrant of the title. He believed in a superior Aryan race comprised of "perfect" genetic specimens. The humiliating defeat of Germany in World War II (as well as World War I) proves it was perfection of a very limited kind.
"Poetry"
"Poetry" that is "easy to understand" symbolizes the propaganda that is so essential to the success of an authoritarian regime. The Nazis rose to power by demonizing all groups opposing their fascist ideology. This was accomplished through simplistic slogans requiring no critical thinking skills. The use of such simplistic "poetry" has proven to be a successful strategy even today.
Human Folly
The tyrant is said to be well acquainted with human folly. In this context, human folly symbolizes the long history of civilization in which millions have supported ideas that work against their own self-interest. Tyranny is oppressive to most living under it, but the folly of humanity is how often the oppressed support their very oppressors.
Senators
A Senator is a political position specifically associated with democracy. The image of "respectable Senators" laughing along symbolizes how tyrants often rise to despotism through the democratic process. Hitler, for instance, first gained power through a democratic voting process.
Crying
Tyrants enjoy more power than any other type of political figure. At the same time, most also claim to be the most victimized people of all. The imagery of children dying when a tyrant is crying symbolizes how tyranny is a system of governance not based on rationality. It is based on personal grievance.
